Highlights
- Infinix has showcased a Solar Charging Case and a Phone with a Solar Panel on the back.
- The firm claims it’s capable of charging the devices at 2W to overcome the standby drain.
- Besides, Infinix also showcased a phone with an E-ink back panel that changes colors depending on the weather or the photo provided.
The Mobile World Congress 2025 serves as a platform for numerous companies to unveil their latest innovations and, notably, to present distinctive device concepts that offer insights into future technology. A noteworthy trend at this year’s event is the emphasis on solar energy. Earlier today, Lenovo introduced its solar-powered Yoga Solar laptop, while Infinix showcased several intriguing concepts, including a device equipped with an integrated solar panel and a case designed to harness solar energy for charging. Additionally, the company revealed a smartphone featuring E-ink technology on its rear. Let us look at both innovations.
Infinix asserts that the solar case employs Solar Energy-Reserving technology, utilizing solar cells composed of a mineral known as Perovskite to capture solar energy. Similar to Lenovo’s Dynamic Solar Tracking System, Infinix’s technology incorporates Maximum Power Point tracking, which optimizes charging efficiency while maintaining a cool temperature for the device.
The company claims that the integrated solar panel can deliver a charging output of 2W, aimed at extending the phone’s standby duration when not actively in use. The case was demonstrated attached to a prototype phone, featuring contact points for charging.
While Lenovo states that its technology can achieve a maximum conversion efficiency of 24%, research from Oxford indicates that Perovskite solar cells may reach a conversion rate of 29.5%. A 2W output is sufficient to maintain the standby battery percentage for an extended period or to provide some level of charging, depending on the power consumption of the device in standby mode, which in contemporary smartphones can range from 0.1W to 0.5W.
Additionally, Infinix introduced a smartphone with a rear panel featuring colored E-ink technology, referred to as E-COLOR SHIFT 2.0 Technology, which is driven by artificial intelligence. Similar to Motorola’s concept phone that analyzes clothing to create a color palette, this Infinix device utilizes AI to adapt its color scheme based on the weather or user preferences. It certainly presents an appealing aesthetic.
